Hope you can add it to one of the Polish sites.
The site shows a beautiful flag, more elaborated than this
one, and mentions as source: Alfred Znamierowski's Book The World Encyclopedia
of Flags (p. 56).

It should be noted, that Wladislaw IV never was king of Sweden. This
was only a title of pretence. His father had been king of Sweden, but was
disposed when he wanted to turn Sweden catholic.
